Y Claims.r (C1. 18S-76) uNnEo y srA'rrzs Parent' cerros This invention relates to bus or car window construction, and more particularly to the top and bottomr rails of a window sash, and the means for connecting them to the side straps joining the I ytop Vand bottom rails together. An object is to provide top and' bottom rails into which the glass may be easily inserted and tightly held, and which at the same time will permit of convenient removal of the glass, particularly in the case of broken pieces which do not protrude from the channelsuiiiciently to catch hold of. A further object is tofprovide top and bottom channel railsv having inherent springiness in their sides, and which at the same time are reinforced longi- 151 tudinally to prevent bowing when the rails are glazed, it being further proposed. to provide such reinforcements which will not detract from the springiness of the sides, and which are further arranged and adapted to limitv the depth to .20 which the glass may be inserted into the rails.

With the above and other objects in View an embodiment of the invention is shown in the accompanying drawing, and this embodiment will be hereinafter more fully described with reference thereto, and the invention will be finally pointed ,out in the claims.

As the construction,'according to the invention, is the same at each side of the window sash, lonly one side will` be shown in the illustrated adaptation of the invention.

Fig. 7 is a horizontal sectional View, taken ,along the 1ine"7 7 `of Fig. 5.

Similar numerals of reference will be used to .denote Vlike parts in the several figures of the y drawing.

the upper and lower ends of the channel, longitudinally extending ribs 2 2 are formed and project toward each other, the space between theseribs being less than the thickness of the window sash glass 3', so that they act as limiting stops to limit the depth to which the glass may be inserted in the channel. The sides of the channel are thickened inwardly at the open ends, as at 4 4, to close in tight about the sides of the inserted glass. The four edges of the glass are bound with glazing tape 5, the edges of `which are trimmed off flush with the rails after insertion of the glass.

The bottom rail 6 is of substantially the Vsame general form as the top rail,.but is of greater height, and within a T-groove 7 in itslower end there is interlockingly engaged the T-rib 8 of a sealing strip 9, of rubber, felt or other suitable sealing material for engaging upon the sill, a slot l0 being formed in its under surface for engaging the weather strip rib of the sill in the usual manner. A pair of longitudinal ribs 11-11 are formed on the inner surfaces of the sides intermediate the upper and lower ends of the channel, and in the base of the channel there is provided a longitudinal groove 12 corresponding in width to the spacing of the ribs and adapted to receive the end rail assembling bracket tongue, as will presently more fully appear. l

The vertical side straps 13, only one of which is shown, are in the form of U-shaped channels adapted to receive the vertical taped edges of the sash glass 3. At the upper end a horizontally projecting bracket tongue 14 is secured between the sides by a rivet 15 in spaced relation below the upper end of the strap, the sides being indented, as at 16 16, so that the rivet heads are below the surface of the strap, and the latter may therefore be inserted in a suitable fixed channel of the window frame to have sliding movement therein. The tongue 14 is assembled with the top rail l simply by inserting it in the end of-the channel between the ribs 2 2, as shown in Fig. 2, and is secured by means of vertically disposed screws 17 17 engaged through counter sunk holes 18 18 in the transverse upper` portion of the top rail and screwed into vertically disposed threaded holes 19 19 in the tongue, the screws drawing the tongue up tightly against the under surface of the upper portion of the top rail.

At the lower endof the side strap a second horizontally projecting tongueKZO is secured by a rivet 21 the sides of the rail being indented, as at 22, in a similar manner to the indentations V16-16 at the upperend. lThe tongue 20 is relaf tively longer, and wider in its vertical dimension, than the tongue 14, and is assembled with the bottom rail by inserting the same in the end of the channel, the lower edge seating in the groove 12 and the upper edge being disposed between the ribs 11-11, and being secured by a pair of transversely disposed binding screws, each comprising a tubular interiorly threaded screw part 23, engaged in a counter-sunk hole 24 in one side of the rail and in an aligned hole 25 in the tongue, and an externally threaded screw part 26 engaged in a counter-sunk hole 27 in the other side of the rail and screwed into the tubular screw part. The engagement ofthese transverse binding screws not only secures the bracket tongue firmly in place, but draws the sides of the rails tightly inwardly toward the glass. Y

The complete assembly of the sash is effected as follows:-

The top and bottom rails 1 and 6 are forced over the glazing tape 5 at the upper and lower edges of the glass, the rails springing open to a slight extent as the glass is forceably inserted, thus insuring a tight binding t of the glass in the channels. The longitudinal ribs 2 2 and 11-11 not only limit the depth to which the glass may be inserted, but provide a longitudinal stiffening reinforcement which permits the sides to spring outwardly and inwardly, but prevents longitudinal bowing of the rails, so that there is a'uniformly tight fit of the rail along the length of the sash. The tendency to bow is particularly pronounced when the sides of the rails are corny paratively thin, so that the longitudinal rein- 355 forcements are especially advantageous in this case. The side straps 13 are forced over the glazing tape 5 at the side edges of the glass, as shown in Fig. 5, the bracket tongues 14 and 20 being inserted in the ends of the top and bottom rails between the ribs 2 2 and 11-11, and are secured in place by the screws 17 and 23-26, as shown in Fig. 2.

Removal of the glass is very readily effected by disengaging the screws and drawing the rails and straps from the edges of the glass. The tape 5 upon the' edge of the glass ts so tightly at times as to hold the glass with sufcient force to make it difcult to remove by pulling, particularly in the case of a broken piece of glass that does not protrude enough to catch hold of. In this case the opening in the rails beneath the edge of the glass permits a drift or pry to' be inserted to force the glass out of the channel.

We have illustrated and described preferred and satisfactory embodiment of the invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof, as dened in the appended claims.

Having thus described our invention what we claimV and desire to secure by Letters Patent is:-
